Fuel Pump Relay

  1. Remove relay from under-hood fuse/relay box. Check relay continuity. Continuity should be present between relay terminals No. 1 and 2, and between relay terminals No. 3 and 4. See Fig 1 and Fig 2 . Continuity should not be present between relay terminals No. 3 and 5. If continuity is as specified, go to next step. If continuity is not as specified, replace relay.
  2. Using a jumper wire, apply battery voltage to relay terminal No. 1. Using a second jumper wire, ground relay terminal No. 2. Continuity should now be present between relay terminals No. 3 and 5. If continuity is not as specified, replace relay. If continuity is as specified, relay is okay at this time.
